*_Section XI_  Toxicological Information*

Routes of exposure: Ingestion, Inhalation, Eye and Skin

Acute Inhalation Effect: None known other than possible temporary discomfort

Acute Ingestion Effect: None expected

Acute Eye Effect: Irritation at high dust levels

Acute Skin Effect: May cause drying of skin

Chronic Inhalation Effect: There is no human data available that
suggests that occupational exposures to synthetic fumed silica will
cause adverse chronic health effects.  Long-term inhalation animal
studies involving a variety of insoluble solid particles have resulted
in chronic inflammation, lung fibrosis and lung tumors in rats.  Tumors
were not observed in similar studies using other animal species (i.e.,
mouse and hamster).  Most inhalation toxicologists feel the tumor
response is unique to rats and not relevant to human exposure. 
Synthetic fumed silica was not used in these tests.  The researchers who
conducted the above studies felt the adverse reactions in the rat were
due to high exposure levels of insoluble dusts overwhelming the lung
clearance mechanisms (lung overload phenomenon) and is not the result of
specific chemical effect of the particulate tested.  This effect is not
expected to occur from occupational exposure to synthetic amorphous silica.
